well The electrons on that shell have nowhere to go so they jump off and become ionised
When an atom gains an electron in its outer shell it becomes a negatively charged ion.
It become an ion with a charge of plus one.
The electrons are the outer shell of the atom
If one or more electrons are lost, the atom becomes a positively charged ion. If one or more electrons are gained, the atom becomes a negatively charged ion.
This atom becomes a cation (negative charge).
The properties of the atom will change.
It becomes a positive ion

It becomes a cation
It becomes a sodium cation with a charge of 1+. Its formula is Na+.
the alkali metals have 1 electron in their outer most shell. in order to obtain a full outer shell they have to lose this electron. so when they react with another metal they lose this electron and the outer most shell.
An ion is an atom with a net electric charge. An ion is formed when an atom either gains or loses a valence electron. Atoms with an unfilled outer shell tend to gain or lose electrons so they can achieve a filled outer shell. Atoms that gain an electron are negative ions, and atoms that lose an electron are positive ions.
